MojoKid writes "Is the world really ready to shift from native apps to HTML5 Web apps? Probably not, at least not in North America yet, but developing nations may see it differently. That's the hope with Firefox OS, a web-based operating system that's (in theory) a lot more open. Of course, one needs only look at Microsoft's battle to get Windows Phone into a place of competition to realize that gaining market share is no easy task, which is why Mozilla will soon be handing out Firefox OS developer phones in order to bolster that. The company's goal is to get app builders to build for Firefox OS, so Mozilla is sending out free Preview handsets for folks to tinker with."

In the U.S., subsidized phones are the norm: for post-paid, long-term contract use, getting a low up-front price on a phone is one of the few upsides. New submitter Apptopia writes "After T Mobile mostly did away with subsidized phone plans, the other major carriers (Verizon, AT&T, Sprint) are paying attention. Carriers lose money with phone subsidies for high-end smartphones (particularly Apple's iPhone). If they do away with the subsidy, you will have to pay full retail price for phones, but your monthly bill will be lower." If people had a better idea what they were paying for, though, manufacturers might fight harder on price. There are lots of well-reviewed, multi-band, unlocked phones on Amazon and DealExtreme from lesser-known companies, and Nokia's new Asha 501 (though limited in many ways, including availability, having just launched in India) shows that the "smartphone" label can apply even to a sub- $100 phone.

An anonymous reader writes "With the personal robotics revolution imminent, a law professor and a roboticist (called Professor Smart!) argue that the law needs to think about robots properly. In particular, they say we should avoid 'the Android Fallacy' — the idea that robots are just like us, only synthetic. 'Even in research labs, cameras are described as "eyes," robots are "scared" of obstacles, and they need to "think" about what to do next. This projection of human attributes is dangerous when trying to design legislation for robots. Robots are, and for many years will remain, tools. ... As the autonomy of the system increases, it becomes harder and harder to form the connection between the inputs (your commands) and the outputs (the robot's behavior), but it exists, and is deterministic. The same set of inputs will generate the same set of outputs every time. The problem, however, is that the robot will never see exactly the same input twice. ... The problem is that this different behavior in apparently similar situations can be interpreted as "free will" or agency on the part of the robot. While this mental agency is part of our definition of a robot, it is vital for us to remember what is causing this agency. Members of the general public might not know, or even care, but we must always keep it in mind when designing legislation. Failure to do so might lead us to design legislation based on the form of a robot, and not the function. This would be a grave mistake."

CowboyRobot writes "Two researchers at San Francisco State University has successfully implemented hardware acceleration for realtime audio using graphics processing units (GPUs). 'Suppose you are simulating a metallic plate to generate gong or cymbal-like sounds. By changing the surface area for the same object, you can generate sound corresponding to cymbals or gongs of different sizes. Using the same model, you may also vary the way in which you excite the metallic plate — to generate sounds that result from hitting the plate with a soft mallet, a hard drumstick, or from bowing. By changing these parameters, you may even simulate nonexistent materials or physically impossible geometries or excitation methods. There are various approaches to physical modeling sound synthesis. One such approach, studied extensively by Stefan Bilbao, uses the finite difference approximation to simulate the vibrations of plates and membranes. The finite difference simulation produces realistic and dynamic sounds (examples can be found here). Realtime finite difference-based simulations of large models are typically too computationally-intensive to run on CPUs. In our work, we have implemented finite difference simulations in realtime on GPUs.'"

crookedvulture writes "Seagate and Toshiba both offer hybrid hard drives that manage their built-in flash caches entirely in firmware. WD has taken a different approach with its Black SSHD, which instead uses driver software to govern its NAND cache. The driver works with the operating system to determine what to store in the flash. Unfortunately, it's Windows-only. You can choose between two drivers, though. WD has developed one of its own, and Intel will offer a separate driver attached to its upcoming Haswell platform. While WD remains tight-lipped on the speed of the Black's mechanical portion, it's confirmed that the flash is provided by a customized SanDisk iSSD embedded on the drive. The iSSD and mechanical drive connect to each other and to the host system through a Serial ATA bridge chip, making the SSHD look more like a highly integrated dual-drive solution than a single, standalone device. With Intel supporting this approach, the next generation of hybrid drives appears destined to be software-based."

For that, Timothy went to Sehome High School in Bellingham, Washington, where members of their Seamonsters robotics team (AKA FIRST Robotics Competition team # 2605; it's a team number, not a date) gave him a good look at their robot's guts, along with showing him how it's controlled and how they organize the 25+ people who work to build and run their robot(s). If you're thinking about joining or starting a FIRST team, this video is essential viewing for you. It's also essential if you just like the idea of robots competing with each other at pyramid-climbing and Frisbee-style disc-throwing. Go, bots, go!

crookedvulture writes "Since their debut five years ago, Intel's low-power Atom microprocessors have relied on the same basic CPU core. That changes with the next generation, which will employ an all-new Silvermont microarchitecture built using a customized version of Intel's tri-gate, 22-nm fabrication process. Silvermont ditches the in-order design of previous Atoms in favor of an out-of-order approach based on a dual-core module equipped with 1MB of shared L2 cache. The design boasts improved power sharing between the CPU and integrated graphics, allowing the CPU cores to scale up to higher speeds depending on system load and platform thermals. Individual cores can be shut down completely to provide additional clock headroom or to conserve power. Intel claims Silvermont doubles the single-threaded performance of its Saltwell predecessor at the same power level, and that dual-core variants have lower peak power draw and higher performance than quad-core ARM SoCs. Silvermont also marks the Atom's adoption of the 'tick-tock' update cadence that guides the development of Intel's Core processors. The successor to Silvermont will be built on 14-nm process tech, and an updated microarchitecture is due after that."

waderoush writes "Consumer Reports calls extended warranties 'money down the drain,' and as a tech journalist and owner of myriad gadgets — none of which have ever conked out or cracked up during the original warranty period — that was always my attitude too. But when I met recently with Steve Abernethy, CEO of San Francisco-based warranty provider SquareTrade, I tried to keep an open mind, and I came away thinking that the industry might be changing. In a nutshell, Abernethy says he's aware of the extended-warranty industry's dreadful reputation, but he says SquareTrade is working to salvage it through a combination of lower prices, broader coverage, and better service. On top of that, he made some persuasive points – which don't seem to figure into Consumer Reports' argument – about the way the 'risk vs. severity' math has changed since the beginning of the smartphone and tablet era. One-third of smartphone owners will lose their devices to drops or spills within the first three years of purchase, the company's data shows. If you belong to certain categories — like people in big households, or motorcycle owners, or homeowners with hardwood floors — your risk is even higher. So, in the end, the decision about buying an extended warranty boils down to whether you think you can defy the odds, and whether you can afford to buy a new device at full price if you're one of the unlucky ones."

The device uses layers of ultrathin materials that can make its wings flap 120 times a second, similar to the rate that a housefly manages. The robot's wings are composed of thin polyester films reinforced with carbon fibre ribs and its 'muscles' are made from piezoelectric crystals, which shrink or stretch depending on the voltage applied to them. Weighing in at just 80 milligrams, the tiny drone cannot carry its own power source, so has to stay tethered to the ground. It also relies on a computer to monitor its motion and adjust its attitude (abstract). Still, it is the first robot to deploy a fly's full range of aerial motion, including hovering (there's a video in the source)."

SternisheFan sends this excerpt from MIT's Technology Review:
"The first comprehensive and large scale smart grid is now operating. The $800 million project, built in Florida, has made power outages shorter and less frequent, and helped some customers save money, according to the utility that operates it. ... Dozens of utilities are building smart grids — or at least installing some smart grid components, but no one had put together all of the pieces at a large scale. Florida Power & Light's project incorporates a wide variety of devices for monitoring and controlling every aspect of the grid, not just, say, smart meters in people's homes. ... Many utilities are installing smart meters — Pacific Gas & Electric in California has installed twice as many as FPL, for example. But while these are important, the flexibility and resilience that the smart grid promises depends on networking those together with thousands of sensors at key points in the grid — substations, transformers, local distribution lines, and high voltage transmission lines. (A project in Houston is similar in scope, but involves half as many customers, and covers somewhat less of the grid.) In FPL's system, devices at all of these places are networked — data jumps from device to device until it reaches a router that sends it back to the utility — and that makes it possible to sense problems before they cause an outage, and to limit the extent and duration of outages that still occur. The project involved 4.5 million smart meters and over 10,000 other devices on the grid."

With the global demand for energy expected to rise by 25 percent in the next 10 years, a renewed effort toward cleaner energy is desperately needed to avoid detrimental effects to the environment and public health. The report says, 'Coal technologies continue to dominate growth in power generation. This is a major reason why the amount of CO2 emitted for each unit of energy supplied has fallen by less than 1% since 1990. Thus the net impact on CO2 intensity of all changes in supply has been minimal. Coal-fired generation, which rose by an estimated 6% from 2010 to 2012, continues to grow faster than non-fossil energy sources on an absolute basis.'"

Revamping the electrical grid from conventionals like coal and oil to accommodate unconventionals like natural gas and solar power will be enormously difficult, economically and technically.' Along these lines, yesterday the U.S. Geological Survey more than doubled their estimate of Bakken shale oil reserve in North Dakota and Montana to 7.4-11 billion barrels.

He also noted that he expects the PC market to pick up in the back half of the year and heading into 2014 as new devices become available."

An anonymous reader writes with this snippet from ExtremeTech: "Researchers at the University of Washington's aptly named Ubiquitous Computing Lab can turn any LCD monitor in your house into a touchscreen, with nothing more than a $5 sensor that plugs into the wall and some clever software." The system works by measuring changes that your hand creates in the electromagnetic signature of the monitor. Surprisingly, it offers some pretty fine-grained detection, too: "full-hand touch, five-finger touch, hovering above the screen, pushing, and pulling." The "$5 sensor" part is mostly theoretical for now to those of us who don't live in a lab, though; on the other hand, "co-author Sidhant Gupta tells Technology Review that the $5 sensor uses off-the-shelf parts, and the algorithms are included in the paper, so it would be fairly easy for you — or a commercial entity — to recreate the uTouch system."

daltec writes "The $250,000 American Helicopter Society Igor I. Sikorsky Human Powered Helicopter Competition prize, unclaimed since 1980, is now closer than ever to being won. With flights up to ten feet in altitude and lasting over 65 seconds, the prize's strict requirements (thought by many to be impossible to satisfy) have all been met — but not on the same flight. Two teams — AeroVelo in Canada and Gamera II at the University of Maryland — are tantalizingly close to claiming the prize. The Gamera team will be making its latest attempt this weekend."

An anonymous reader writes "Btrfs is the next-gen filesystem for Linux, likely to replace ext3 and ext4 in coming years. Btrfs offers many compelling new features and development proceeds apace, but many users still aren't sure whether it's 'ready enough' to entrust their data to. Anchor, a webhosting company, reports on trying it out, with mixed feelings. Their opinion: worth a look-in for most systems, but too risky for frontline production servers. The writeup includes a few nasty caveats that will bite you on serious deployments."

o2binbuzios writes "Due to an office move, I have a chance to do a clean-sheet design for an integration room at a fairly large VAR ($100M+ ). I'm looking for some ideas or best practice to support 100-120 square meters (~50 x 30 ft). I'm particularly interested in ideas around efficient workflow, ways to manage cabling and electrical, and 'environmental' solutions that make it a pleasant place to work. There will be a central bench with 6-8 stations (3-4 per side) with engineers and techs who may be configuring stacks of up to 10 devices at a time that could range from servers, to network elements, to SAN & NAS devices and more. I've been looking for a paper that seems like it must exist — but I'm happy to gather good ideas one at a time or in bunches here on Slashdot."

concealment writes "Sparkler Filters up north in Conroe [Texas] still uses an IBM 402 in conjunction with a Model 129 key punch – with the punch cards and all – to do company accounting work and inventory. The company makes industrial filters for chemical plants and grease traps. Lutricia Wood is the head accountant at Sparkler and the data processing manager. She went to business school over 40 years ago in Houston, and started at Sparkler in 1973. Back then punch cards were still somewhat state of the art."
See kottke.org for an eye-popping view of one of the "programs" — imagine debugging that.

coondoggie writes "When it comes to fixing broken systems, especially in remote locations, engineers could soon turn to a new mobile robotic system IBM is developing that could help them more easily find the broken equipment, offer up information about the system and provide real-time visual support from supervising experts. The mobile maintenance, repair and operations prototype includes an application that lets a supervisor monitor an engineer's progress towards the maintenance site, and a robotic arm coupled with a camera system, a microphone and laser pointer."

An anonymous reader writes "Hui Zhang and Shangui Zhao describe China's decision to move ahead with nuclear power. Following the Fukushima Daiichi accident, China slowed its rapid expansion of nuclear power and undertook a major reevaluation of safety practices. The government has now resumed approval of new nuclear power projects, and is cautiously moving forward. Good description of safety issues that remain."
They are suspending in-land construction, and are aiming at 58GWe instead of 80GWe of generation capacity by 2020. It's still more than the 40GWe they planned to build under their 2007 plans.

An anonymous reader writes "Today AMD has officially unveiled its long-awaited dual-GPU Tahiti-based card. Codenamed Malta, the $1,000 Radeon HD 7990 is positioned directly against Nvidia's dual-GPU GeForce GTX 690. Tom's Hardware posted the performance data. Because Fraps measures data at a stage in the pipeline before what is actually seen on-screen, they employed Nvidia's FCAT (Frame Capture Analysis Tools). ... The 690 is beating AMD's new flagship in six out of eight titles. ... AMD is bundling eight titles with every 7990, including: BioShock Infinite, Tomb Raider, Crysis 3, Far Cry 3, Far Cry 3: Blood Dragon, Hitman: Absolution, Sleeping Dogs, and Deus Ex: Human Revolution."
OpenGL performance doesn't seem too off from the competing Nvidia card, but the 7990 dominates when using OpenCL. Power management looks decent: ~375W at full load, but a nice 20W at idle (it can turn the second chip off entirely when unneeded). PC Perspective claims there are issues with Crossfire and an un-synchronized rendering pipeline that leads to a slight decrease in the actual frame rate, but that should be fixed by an updated Catalyst this summer.

cylonlover writes "Teaching a robot how to deal with real-world problems is a challenging task. There has been much progress in building robots that can precisely repeat individual tasks with a level of speed and accuracy impossible for human craftspeople. But there are many more tasks that could be done if robots could be supplied with even a limited amount of judgment. A robotics group led by Professor Sylvain Calinon at the Italian Institute of Technology is making progress in solving this problem and has developed a robot whose purpose in life is to help a person build an IKEA table."
